Specification of Letters Patent.

Patented March 5, 1907.

Application filed June 26,1906. Serial No. 323.424.

T0 all whom, it may concern: I l l Be it known that I, VVILLIAM M.HENDER- SON, a citizen of the United States, residing in the town ofHigh Spire, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Movable-Point Crossings,of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, of which- Figure 1 isa plan View of a movable-point crossing, showing my invention appliedthereto. 2 is an enlarged plan view showing one of the movable-pointrails embodying my invention. Fig. 3 is a section on line I i) '0, Fig.2. Fig. 4 is a section on line at x,

I l l r Fig. 2. Fig. 5 is a section on line y y, Fig. 2. Fig. 6 is asection on line 2 2, Fig. 2. Fig. 7is an elevation taken on line a a,Fig. 1.

The object of this invention is to provide the point-rails of amovable-point crossing with a hard-metal point of unique construc tionand at the same time to provide said I point-rails with a suitablepick-up device for I guttered wheels, which pickup device shall I beintegral with the hard-metal point portion.

The precise character of the invention will appear from the followingdescription.

In the drawings, 1 designates the usual main-track rails bent to formthe knuckle l designates the movable rails, each of which in thisinstance terminates some distance to the rear of said knuckle, as seenin Figs. 1 and 2. A hard-metal point-forming piece 4 constitutes anextension of the said point-rail 3 and has extending on the outer sideand to the rear end of the said point-rail an extension 5, the to of thehead of which I is in the same plane as the head of the pointrail, butits outer end is at 6, as seen in Fig. 2. The web portion 7 of p theextension 5 abuts against the web of the l point-rail 3 and extends forthis purpose beyond the end of said extension 5 and beneath l the headof the point-rail 3, as seen in Fig. 6. The said web portion 7 iscontinuous with the web portion 7 of the hard-metal pointpiece inadvance of the end of the point-rail. Extending from the point of saidpointl forming piece and lying against the web 7 l thereof throughoutits length and then 1 against the web of the point-rail 3 to a pointopposite the end of the web extension 7 is a l beveled downwardly Irolled-steel strap-piece 8. Said strap-piece is secured to the web 7 ofthe point-forming piece by bolts 9, passing through the web 7 andthrough said strap-piece, as seen, and the strap 8, point-rail 3, andhard-metal piece 4 are secured together by bolts 10 passing through thestrap 8, the web of the point-rail, and the web extension 7 of the saidhard-metal piece, thus firmly securing the said hard-n1etal piece,point, and strap together. The strap-piece 8 is also provided with afoot-flange 11, to which may be attached the usual switch-bars 12, thusavoiding the attachment of said bars 12 to the hard-metal piece 4., saidhard-metal piece being usually of cast metal.

By making the point portion of the pointrails 3 of hard metal thebreaking down of the point under the hammer-blows of passing wheels isavoided, and by providing the heac extension 5 with its beveled portion6 on the outer side of the point-rails 3 if a wheel passing over thepoint-rail should be gutteredthat is, have a false flange on its outerside said false flange will ride up the inclined portion 6 onto the headextension 5, and so be uplifted to the plane of the head oi thetrackrails 1, over which it will pass without wearing a groove therein,as would otherwise be the case.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a movable-point crossing, the combination, withthe knuckle-forming trackrail, of the movable-point rails, terminatingsome distance on each side of the knuckle, the hard-metal point-formingpiece, whose upper surface is in the same plane as the said point-rail,said point-forming piece having the rearward extension adjacent theouter edge of the head of the point-rail; together with means forsecuring said point-rail and hard-metal point-forming piece together,substantially as set forth.

2. In a movable-point crossing, the combination, with theknuckle-Forming trackrail, oi? the movable-point rails, terminating somedistance on each side of the knuckle, the hard-metal point-forming piecewhose upper surface is in the same plane as the said point-rail, saidpoint-forming piece having the rearward extension adjacent the outeredge of the head of the point-rail, and whose free rear end isdownwardly beveled; together with means for securing said pointrail andhard-metal point-forming piece together, substantially as set forth.

3. In a movable-point crossing, the combination, with theknuckleiorniing trackrail, of the movable-point rails, terminating somedistance on each side of the knuckle, the hard-metal point-formingpiece, whose upper surface is in the same plane as the said point-rail,said point-forming piece having the rearward extension adjacent theouter edge of the head of the point-rail, and having also a web portion,together with the strappiece extending the length of the point-for1ningpiece, its forward portion lying against the web of the latter, and itsrear portion against the web of the point-rail; together with the boltssecuring saidpoint-forining piece, point-rail, and strap, together,substant ally as set forth.

4. In a movable-point crossing, the combination, with theknuckle-forming trackrail, of the movable-point rails, terminating somedistance on each side of the knuckle, the hard-metal. point-formingpiece, whose upper surface is in the same plane as the said l pointrail,said point-forming piece having the rearward extension adjacent theouter edge of the head of the point-rail, and having also a web portiontogether with the strappiece extending the length of the point-formingpiece, its forward portion lying against the web of the latter, and itsrear portion against the web of the point-rail; the foot extension ofsaid strap-piece; together with the bolts securing said pointfor1ningpiece, point-rail, and strap together, substantially as set forth.

In testimony whereof I have hereunto affixed my signature.
